1 Claim. (01. 257-242) This invention appertains to new and useful material inlet header 10, with the supply pipe 11 improvements in means for reclaiming heat. leading thereto. Numeral 12 represents a trap from waste materials, the principal object being door which is opened by the flow of the heated to provide a device whereby the waste heat rewaste material from the header 10. This header maining in any liquid or free flowing solution it) rests upon the cool water header 13 which has 60 or substance after processing may be reclaimed an inlet conduit 14. Couplings 15 connect the by transference by conduction through the walls header 13 to a plurality of tubes 16 which extend of conduits to a cooler liquid which in this form along the bottom of the trough 8, in the manner can be utilized for commercial purposes. clearly shown in Figures 2 and 6.
